I think they are a year or 2 old. My buddy that has a Hi-Fi shop took them in on trade, and let me take them to get my impressions. From what you say the M22i is drastically different than the M3’s you had. That is interesting. The M2 and m3 are crossed over at 2.7, and 2.2, whereas the M22s are crossed over at 3.5kHz, perhaps that is why these little ones seem so bright.
